This important volume deals with the issue of how to make comparisons in the field of human development. In their comparisons of various social groups, social scientists generally focus on what the differences are, rather than elucidating how and why the groups differ. Comparisons in Human Development examines ways in which different disciplines have treated comparisons and development and provides empirical examples that take a comparative, developmental approach to human activity and thought. Contributors share the view that the study of development must be concerned with processes that operate over time and are regulated by their physical, biological, social and cultural contexts. Development is understood in systemic terms, with multidirectional influences that cross levels of analysis, including the cellular, the individual, the family, and the cultural and historical.
